The growth of the human body ends at the age of 25, and the aging process begins immediately. To slow down or stop it altogether is a dream not only of scientists and philosophers who have been trying for centuries to find the “elixir of youth”, but also of each individual person. About a century ago, the science of gerontology arose, studying the biological, social and psychological aspects of human aging, its causes and ways to deal with it. A lot of scientific and pseudo-scientific theories of aging have arisen, over which whole gerontological institutes work, created in almost all countries of the world. There are a lot of theories describing the causes of aging – a change in the regulation of gene activity, a decrease in the synthesis of intracellular regulators of plasma membranes, a decrease in the length of telomeres (end sections of chromosomes), the concept of stress-age syndrome, etc. Continue reading
The topic of losing weight is, without exaggeration, one of the most popular topics in communication – both physical and virtual, and in all age groups.

Currently, there are mainly two directions: veganism and lacto-ovolacto-vegetarianism. Veganism is the most severe form, including eggs and animal milk (except human breast milk for babies). As a rule, the path to veganism passes through first of all awareness of the ethical problems of modern society and involves the maximum rejection of the use of products obtained through the exploitation and killing of animals.
The word vegan was proposed by the ideologist of this trend Donald Watson in the middle of the last century as an integral part of the first three and last two letters of the English word “vegetarian”. This term was introduced by the “Vegan Society”, founded by Watson in the UK. Continue reading
